Power Supply or the power supply to the devices of the computer. The main functions of the Power Supply is AC power converter (AC) into direct current (DC) to the power supply to the devices inside the computer's motherboard, hard disk, CD-ROM disks, ฟล็อปิ้, etc., as well as some external connected devices e.g., mouse, and monitor, scanner, khibod, etc.Electricity used by the House to fire AC 220 volts, but the power it will use computer equipment to power the voltage DC power is low. Your computer must have a power supply and output functions as an external t-level flow is computer equipment can be used.Power supply componentsPower supply will look like a rectangular box mounted on the corner of the case. At the rear is a plug for plug power cord into a household outlet with fan for the heat Supply to the list itself, including the heat under the case.Usually the voltage power supply to the device is voltage magnitude 3.3 and 5 volts, which is paid to the lighting circuit (Digital Circuits), while the 12 volt sizes, pressure will be used to run the motor in the daira and discharge fan. Properties of Power Supply units Watts (Watts) by the value of this pressure has come from Watt (Voltage) In the unit of Volt (Volts) and power (Current) in the unit ampere, or amp (Amperes or Amps)
